Fractional Day Clock!

Enjoy the convenience of representing time within a date using a fraction of a day!¹

No more pesky hours, minutes, and seconds!

Scale comparisons

• .1 D is 2.4 hours
  • or 2 hours and 24 minutes - half of that is roughly an hour
• .01 D is 14.4 minutes
  • or 14 minutes and 24 seconds
• .001 D is 1.44 minutes
  • or 1 minute and 26.4 seconds - roughly a minute
• .0001 D is 8.64 seconds
• .00001 D is .864 seconds
  • roughly a ‘normal’ second, but uncomfortably shorter

More comparisons

• An average song is about 0.0025 D long
• An average movie is about 0.083 D long
• A pomodoro technique uses 0.017 D per interval
• You should sleep for about 0.33 D a day

Converting from normal time to decimal

I couldn’t be bothered setting up a nice form for this yet.

However, you can use a simple formula:

fracD = (H / 24) + (M / 1440) + (S / 86400)

Substitute H for hours, M for minutes, S for seconds. You’ll get the fractional part of the day. I prefer to convert to UTC time before applying this, to yield consistent times no matter what/where one is.

An hour is about 0.04166667 of a day. This seems rather inconvenient for mental arithmetic with hourly timezones.
